SPRING MOUNTING Application filed September To all whom it may concern:

Be it known that I, FREDERICK H'AeonR Hnannnv, a subject of the King ofGreat Britain, residing at-' Stirling Road, Edgbaston, Birmingham, inthe county of /Varwick, England, manufacturer, have invented certain newand useful Improvements in the Spring Mountings of Vehicle Seats, ofwhich the following is a specification.

This invention relates to the spring mounting of vehicle seats, in whichan up per frame is supported from an under frame by springs. The presentinvention comprises improvements in 'the springing of such seats,whereby a substantially parallel springing action of said seat isobtained, while at the same time the seat is retained against unduemovement in both lateral and longitudinal directions through the mediumof a rigid connecting element pivotally connected to the upper and lowerframes of the seat. The improvements in the case of pillion seats ofmotor cycles are of such a nature, as to permit of a seat bottom ofsheet metal, thus obviating the necessity of the increased heightrequired for the upholstering of the seat, the seat being also adaptedfor the ready and alternative attachment of such accessories as a backrest and foot rest in case of the seat being used as aside seat, footrests and back supports in the case of the seat being used for riding inthe jockey posit-ion with the addition of a suitable hand grip at eitherone or both ends, or alternatively with the rear hand grip of a tool boxor wallet, all of which are made readily interchangeable.

In order that this invention may be easily iuiderstood and readilycarried into practice, reference may be had to the appended sheet ofdrawings, in which Y Figure 1 is a perspective View of the presentinvention constructed in the orm of a pillion seat.

Figure 2 is a longitudinal section through the seat shown in Figure 1.

Figure 3 is a plan view of the same seat with the bottom removed.

Fig. 4 is a side elevation showing a conventional form of motor cycle indotted lines and the invention in solid lines and in operative positionthereon.

In an embodiment of this invention as applied to a pillion seat, thelower frame of the seat which is adapted to be attached HAGGER HEADLEY,or BIRMINGHAM, ENGLAND, assrenon' ro TAN sAn ENGLAND, A CORPORATION.

to the luggage carrier is formed of two longitudinal bars a having theirbroad sides arranged vertically, such bars a being connected together ateach end by two lateral bars a having theirupper faces arrangedhorizontally and being turned up to a'right angle at each end to formflanges which em- I brace the longitudinal bars a, and to which thelongitudinal bars are riveted at the respective four corners of thelower frame.

The upper frame is formed of two similar horizontal bars 2) except thatsuch longitudinal barsare'curved slightly downwards at the centre andthe transverse bars .6 at each end are turned down toembrace the ends ofthe longitudinal bars 5 to which they are riveted.

A plurality of coiled springs 0 are arranged between the upper and lowertransverse bars 6 a at each end of the seat, the upper and lower end ofsuch spring 0 being secured to the respective upper and lower bars by a.second strip (Z, which in each case is inserted through the end coils ofthe spring 0, which end coils are clamped tightly between the two barsby the insertion of screws 6 through the frame bars, which screws 6 areadapted to engage in tapped holes in the strips d.

For retaining the upper frame against undesired movement in both alateral and longitudinal direction a. U-shaped member f is provided, theends of the U being pivoted to the lower longitudinal bars a at pointsadjacent the one end of the saddle, while the other end of the U-memberf is pivoted on each side to the upper longitudinal bars Z) at a pointrearwardly of the centre of the saddle considering for this purpose thatthe ends of the U-shaped member are pivoted to the lower frame at thefront end, the sides of the U-shaped member being slightly bent so as toavoid contact-with the lateral bars X provided for securing the seattothe carrier when the seat is laterally depressed under its springaction. 7

The seat bottom g is formed of sheet metal, slightly curved downwardstowards the centre of its length, and having its longitudinal edgesturned over to avoid the exposed edge of the meta-l. The seat bottom issecured in position by the same screws 6 which enter the springclamping-- strips (Z.

The ends of the longitudinal bars 6 of the upper frame are bent over toform inwardly projecting-flanges b? which are each provided with atapped hole by which-bars carrying the seat back, side foot rest, jockeyfoot rest, hand grip. or grips, tool box or wallet are adapted tobeattached by suitable screws it which engage with thetapped holes, theflanged projections 6 preferably being bent to a position which isslightly past the right angle, so that when the flangesare drawn uptightly to the bar which supports the accessory, the amount of spring inthe flanges 6 forms a locking mediumin relation to the attachment screwit in each case: JPivotal' parts of the saddl are all substantiallyriveted so as to obviate any and bracingme-nibcr also arrangedbetweensaid frames, said member having one. end pivotally connected tothe lower frame at a point near one end of the'latter and having theopposite end. pivotally connected to the upper 'frame'at a point nearbut be'yoiid the center thereof with relation to the pivot point of saidconnecting and bracing member in the lower frame, the axes of thepivotal connections being relatively fixed.

2. A spring seat for vehicles and the like,

com risin a lower frame an 11') er frame comprising a pair of side barsand a pair of end bars connecting the side bars and-hav ing downturnedend portions secured thereto, .said' side bars having inwardly turnedend portions and attaching screws mounted in said end" portions, andsprings between the frames, and yieldingly supporting the upper frame,the upper and lower ends of said springs being secured to said frames.

In witness whereof I have hereunto set my hand.-
